⚡ FastAPI 🔷 Supabase ⚛️ React + TypeScript 💳 Stripe 🚂 Railway ▲ Vercel

You already know Python.
You shouldn't have to learn a new stack to ship.

Every SaaS starter kit — ShipFast, Makerkit, Supastarter — is built on Next.js. If you're a Python developer, you're stuck setting up auth, payments, and database from scratch every single time. That's 3–7 days of plumbing before you write a single line of product code.

ShipFast.py fixes this. Clone the repo, fill in your env vars, and you're shipping.

How it works

1

Buy & get access

Enter your GitHub username at checkout. You get a collaborator invite within seconds — no waiting, no manual steps.

2

Clone & configure

Clone the repo, fill in your .env file with your Supabase, Stripe, and Railway keys. The README walks you through every variable.

3

Deploy & build

Push to Railway and Vercel. Everything works. Start writing the code that's actually your product — not boilerplate.

Everything wired, nothing left to set up

Every piece works out of the box when you clone the repo.

Auth — done

Email + password signup, Google OAuth, JWT validation on every FastAPI endpoint, protected frontend routes, session persistence.

Stripe — wired

Subscription and one-time checkout, Customer Portal, webhook handler for all lifecycle events. Billing page included and working.

Supabase + RLS

Postgres schema with migrations ready to run. Row Level Security policies pre-written so users can only access their own data.

FastAPI backend

Python. User CRUD, admin role gate, rate limiting, CORS, JWT middleware. Not Flask. Not Django. FastAPI — the way you want it.

React + Tailwind frontend

Login, signup, dashboard, settings, billing — all built in TypeScript. Clean Tailwind design you can customize in minutes.

Deploy configs included

Railway config for FastAPI. Vercel-ready for the frontend. Docker Compose for local dev. README gets you live in under 30 minutes.

FAQ

What do I get after buying?

Enter your GitHub username at checkout. Within seconds you'll get a GitHub collaborator invite by email. Click accept → clone the repo → start building. No waiting, no manual steps.

Is this a subscription?

No. One-time payment. Lifetime access to the repo including all future updates pushed to it.

Do I own the code?

Yes. Use it in unlimited personal and commercial projects. You can't resell the kit itself or redistribute it to others.

What's the difference between the two editions?

The base edition ($149) is the full SaaS starter kit — FastAPI, Supabase, React, Stripe, deploy configs. The AI Edition ($249) includes everything plus a Claude AI chat interface pre-wired with streaming SSE, per-user credit system, and a full chat UI component. If you're building an AI product, get the AI Edition.

What if I don't know React?

The frontend is straightforward React with Tailwind. If you know Python and FastAPI, you'll be able to read and modify it. The README walks through the folder structure in plain terms.

Why not Next.js like every other starter kit?

Because you're a Python developer. ShipFast.py is the only starter kit with Python/FastAPI at the center. The React frontend is deliberately simple so your Python skills stay relevant.

What services does this require?

Supabase (free tier works), Stripe (free to set up), Railway (free tier works early on), Vercel (free tier). You can run everything for $0/month until you have real traffic.

What if I need help?

File an issue on the GitHub repo. No SLA, no Discord — but issues get looked at regularly.

Stop setting up. Start shipping.

The stack is ready. The plumbing is done. You just need to build the product.
